D2D relaying strategy is conceived as an attractive enhancement technique as the complement for D2D communication which can extend the communication range and further improve the system performance. Considering users' selfishness, we establish a new D2D cooperate relaying paradigm by leveraging two social factor: social tie and reputation. Tie strength with the source decides how much power can be provided by relay users. The cooperation probability modeled by the combination of reputation and social tie reflects the user's forwarding willingness. Then we propose two social- aware relay schemes considering the impact of social tie and reputation. Simulations results show that there is a trade-off between the cooperation probability and transmission rate of the potential relay user, the proposed schemes can greatly improve the performance in different cases.
